302-004-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-004-621-201 is a standard card edge connector from the 302 series, designed for dual-edge PCBs with a 0.050 inch (1.27mm) contact spacing. It features four female contacts with gold flash plating and cantilever spring terminals. The housing is black polyamide (PA66/nylon 6/6) without mounting lugs, intended for through-hole termination. This component supports board thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm) and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with cantilever spring contacts for reliable signal transmission
• Gold flash plated terminals ensure corrosion resistance and low contact impedance
• Black PA66/nylon 6/6 housing provides durable insulation without integrated mounting lugs

Edgeboard Connectors Applications

• Interconnection in medical electronic devices requiring high reliability
• Industrial control systems utilizing double-sided circuit boards
• General-purpose electronics employing standard 1.27mm pitch card edge interfaces

Edgeboard Connectors Procurement Notes

Verify availability status as supply may be restricted or limited depending on the region. Confirm that the specific ordering suffix matches the required contact count and plating specifications. Ensure compatibility with the target PCB thickness range of 1.30mm to 1.80mm before finalizing procurement orders to prevent mechanical fit issues.

Edgeboard Connectors Selection Notes

Select this model when a compact, four-position dual-edge connector is required for space-constrained designs. The 1.27mm pitch allows for high-density routing on smaller boards. Choose this variant over single-edge models if the application utilizes double-sided PCBs. Verify that the absence of mounting lugs aligns with the mechanical assembly strategy.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 series, which specializes in standard card edge connectors with fine 1.27mm spacing. The series is widely utilized in applications demanding robust interconnect solutions for double-sided circuit boards. The 302-004-621-201 represents a specific configuration within this family, offering a minimal pin count for simple interface requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 1.27mm pitch, dual-edge orientation, and four-pin count. Compatible alternatives include other EDAC 302 series variants with different pin counts or housing colors, provided they match the mechanical dimensions and electrical ratings.
